EFFECTS OF OVEREXPOSURE

CONTACT WITH SKIN OR EYES MAY CAUSE SEVERE IRRITATION OR BURNS.

EXCESSIVE INHALATION OF DUST IS IRRITATING AND MAY BE SEVERELY DAMAGING

TO RESPIRATORY PASSAGES AND/OR LUNGS.

INHALATION MAY CAUSE NAUSEA, VOMITING AND DIFFICULT BREATHING.

INGESTION MAY CAUSE NAUSEA, VOMITING, HEADACHES, DIZZINESS,

GASTROINTESTINAL IRRITATION.

INGESTION MAY CAUSE IRRITATION AND BURNING TO MOUTH AND STOMACH.

PROLONGED EXPOSURE MAY INCREASE BONE DENSITY, STIMULATE NEW BONE GROWTH

OR CAUSE CALCIUM DEPOSITS IN LIGAMENTS. MOTTLING OF TOOTH ENAMEL MAY

OCCUR.

TARGET ORGANS

EYES, SKIN, RESPIRATORY SYSTEM, CENTRAL NERVOUS SYSTEM, KIDNEYS

MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE

NONE IDENTIFIED

ROUTES OF ENTRY

INHALATION, INGESTION, EYE CONTACT, SKIN CONTACT

EMERGENCY AND FIRST AID PROCEDURES

CALL A PHYSICIAN.

IF SWALLOWED, IF CONSCIOUS, IMMEDIATELY INDUCE VOMITING.

IF INHALED, REMOVE TO FRESH AIR. IF NOT BREATHING, GIVE ARTIFICIAL

RESPIRATION. IF BREATHING IS DIFFICULT, GIVE OXYGEN.

IN CASE OF CONTACT, IMMEDIATELY FLUSH EYES OR SKIN WITH PLENTY OF WATER FOR

AT LEAST 15 MINUTES WHILE REMOVING CONTAMINATED CLOTHING AND SHOES.

WASH CLOTHING BEFORE RE-USE.

7 - SPILL AND DISPOSAL PROCEDURES

------------------------------------------------------------------------------

STEPS TO BE TAKEN IN THE EVENT OF A SPILL OR DISCHARGE

WEAR SELF-CONTAINED BREATHING APPARATUS AND FULL PROTECTIVE CLOTHING. STOP

LEAK IF YOU CAN DO SO WITHOUT RISK. VENTILATE AREA. CAREFULLY NEUTRALIZE

SPILL WITH DILUTE HCL. FLUSH AREA WITH FLOODING AMOUNTS OF WATER. (USE

CAUTION.)

DISPOSAL PROCEDURE

DISPOSE IN ACCORDANCE WITH ALL APPLICABLE FEDERAL, STATE, AND LOCAL

ENVIRONMENTAL REGULATIONS.

------------------------------------------------------------------------------

8 - PROTECTIVE EQUIPMENT

------------------------------------------------------------------------------

VENTILATION: USE ADEQUATE GENERAL OR LOCAL EXHAUST VENTILATION

TO KEEP FUME OR DUST LEVELS AS LOW AS POSSIBLE.

RESPIRATORY PROTECTION: NONE REQUIRED WHERE ADEQUATE VENTILATION

CONDITIONS EXIST. IF AIRBORNE CONCENTRATION

EXCEEDS TLV, A DUST/MIST RESPIRATOR IS

RECOMMENDED. IF CONCENTRATION EXCEEDS CAPACITY OF

RESPIRATOR, A SELF-CONTAINED BREATHING APPARATUS

IS ADVISED.
